Washer-dryer shows E12 during drying; the drum may turn but there is no heat or the cycle aborts.

Safety: Unplug the appliance. Internal metal edges can be sharp; wear gloves.

• Clean condenser and ducts: Remove the condenser unit (if accessible) and rinse it thoroughly to remove lint and scale. Clean all reachable ducts and lint traps.
• Check fan operation: Start a drying cycle briefly (with panels in place) and listen for the fan. If there is no fan noise, stop the machine and proceed with internal checks.
• Access fan motor: Remove the top or rear panel to locate the dryer fan housing. Inspect the fan impeller for broken blades or obstructions.
• Test fan motor: With power off, spin the fan by hand; it should rotate freely. Check the motor's resistance with a multimeter. An open circuit indicates a failed motor.
• Inspect wiring: Ensure the fan motor connector is secure and the wires are intact.
• Replace fan assembly: If the motor is faulty or the impeller is damaged, replace the complete fan motor assembly.
